As far as i can see there are two possibilities.
First: Daniel placed the camera on the floor and set it up so it could see the bed but not be seen by Lana, deliberately, in order to broadcast/record his sex session with Lana to recover money stolen from him by Kiara, from donations received for the Daniel/Lana performance from Kiara/Sharon fans. Since cameras are secured on tripods by screws, if the camera turns out to be off the tripod on the floor, someone must have removed and put it there indicating Daniel as the culprit.
(Will Lana find out?)
Second: Daniel is unaware that the camera is still functional and focused on the bed, and doesn't realize that his sex session with Lana will be broadcast/recorded, with Kiara/Sharon benefiting later from the large amount of money, donated by their subscribers, not for their own content but for the Daniel and Lana show.
(Will the girls be able to work out what went on?)
Since the whole silly set up for this chapter of ID is for Daniel to get enough money from Kiara and Sharon, to book a place on the Mother-Son camp, I reckon the first possibility seems most likely. The fact Daniel was desperate to penetrate Lana as soon as possible but chose to masturbate her to orgasm instead, with her incredible backside in full view of the camera for all to see, looks suspiciously like he was trying to encourage Kiara/Sharon's webcam audience to donate as much as possible to keep the new content flowing. If the second possibility is true then Daniel will have to discover that he put on a porn show with Lana, after the event, and try to get the money he needs from Kiara/Sharon later, by confecting some peculiar explanation how so much money rolled into their bank accounts while they were bound and unconscious and that some (or all) of it showld be his.
I am kind of intrigued to see how this farce plays out.
